centric 7 is brought into contact With the roller G, it forces the hellcrank 9 and the escapement loer 8 hack to their normal pon sitions, andthe trigger il, under the action of gravity, assumes its operativeposition and locks the seid parts 9 and 3 in their nor1 mal positions. 4

The time required :for the eccentric 7 to make its rotation, and hence,for 'the escapeznent bar 3 to malte its downward and return movement, issuiiicient to permit therelease or" the first or lowest matrix, lint notof the next following matrix, and. hence, escapement lngl 5 of the saidbar 3 Will engage the lower end of the upper lng or' 'the' secondmatrix, which second matrix then, of course becomes the first orlowermost matrix. lt will thus he seen that this device insures therelease of but one matrix under any one key depression, and it make nodifference how long the said lief,7 ma;T be held depressed. Theescapement actuating mecha nism, above described, may he, andpreferablyY is, employed with the multiple maga zine and escapementmechanism shown in 2 and 3. ln this multiple magazine machine, theseveral independent magazines 19 are shown as inclined, and one locatedover the other, and the escapement bar is made up oi' a. main section 2Gand a multiplicity of separate but supplemental sections 2l, of whichlatter, there is one for the corresponding,l or overlying channel oi'each magazine. These supplemental sec tions 2l are provided withlaterally projecting escapement lugs 22 that ivorlr through clearancepassages in the bottoni vof the respective magazines and engage the ingsof matrices in the same manner as lo the lugs 5 of the escapement bar 3,shown in Fig., l. The supplemental bar sections 2l may he yieldably helddown by grav'ty or by the action of gravity and the coperating aetion oflight springs 23. in Fig. 3,. the numeral 2l indicates selecting hars,one for each magazine which operate in a known manner te determine themagazine from which matrices 'will be discharged under actions of theescapement mechanism.

ln the arrangement illustrated in Fig. l, the numeral 25 indicates anupright maga zine havingA in one side nerforations through which Werl:eseapement lugs 26 formed on the upper ends`oi` escapement levers 27,
